intl_generator 0.4.0

Contains code to deal with internationalized/localized messages, date and number formatting and parsing, bi-directional text, and other internationalization issues.

Intl_generator

This is a fork of intl_translation to have an up to date version.

If you prefer having translations as part of your build_runner process or need to support flavors, please check intl_flavors

This package provides message extraction and code generation from translated messages for the Intl package. It's a separate package so as to not require a dependency on analyzer for all users.

Extracting And Using Translated Messages

When your program contains messages that need translation, these must be extracted from the program source, sent to human translators, and the results need to be incorporated.

To extract messages, run the extract_to_arb.dart program.

  pub run intl_generator:extract_to_arb --output-dir=target/directory
      my_program.dart more_of_my_program.dart

This will produce a file intl_messages.arb with the messages from all of these programs. This is an ARB format file which can be used for input to translation tools like Localizely or (the deprecated) Google Translator Toolkit. The resulting translations can be used to generate a set of libraries using the generate_from_arb.dart program.

This expects to receive a series of files, one per locale.

pub run intl_generator:generate_from_arb --generated-file-prefix=<prefix>
    <my_dart_files> <translated_ARB_files>

This will generate Dart libraries, one per locale, which contain the translated versions. Your Dart libraries can import the primary file, named <prefix>messages_all.dart, and then call the initialization for a specific locale. Once that's done, any Intl.message calls made in the context of that locale will automatically print the translated version instead of the original.

import "my_prefix_messages_all.dart";
...
initializeMessages("dk").then(printSomeMessages);

Once the Future returned from the initialization call completes, the message data is available.
